150L 200L 300L Integrated Pressurized Flat Plate Solar Geysers

Flat Plate Solar Geysers – Working Principle

A flat plate solar geysers is a thermosyphon system in which the flat plate collector is positioned below a high-pressure hot water tank. The collector and tank are connected by two circulation pipes, forming an open-loop solar water heating system that uses only water as the circulation medium. As the sun heats the water directly inside the flat plate collector, the heated water rises naturally and is stored in the hot water tank, ensuring a continuous supply of hot water.

Flat Plate Solar Geysers – Description

The Riwatt flat plate thermosyphon integrated system consists of a solar flat plate collector, water storage tank, mounting bracket, circulation pipes, and accessories. Based on the thermosyphon principle, the collector absorbs solar energy to heat the water directly, while the natural circulation transfers the hot water into the storage tank for convenient use.

Frequently-Asked-Questions (FAQ)

1. What is  Flat Plate Solar Geysers?

Flat Plate Solar Geysers is a kind of solar hot water heating system for heating water using energy from the sun. Solar energy is collected by a flat plate solar collectors, which is then connected by pipes to a hot water storage device such as a hot water cylinder.

2. What are the Benefits of Flat Plate Solar Geysers?

Flat Plate Solar Geysers can help save water heating costs by reducing the amount of gas and electricity needed to heat water. By using sunlight to heat water instead of combustible sources or fossil fuel-produced electricity, fewer pollutants are being introduced into the environment. Solar energy is not affected by the current shortage of electricity and does not stop providing hot water during load shedding.

3. How Much of My Total Hot Water Requirements Can a Flat Plate Solar Geysers Provide?

A Flat Plate Solar Geysers can provide between 50% and 90% of your total hot water power requirements, depending on the climate and model of heater. When you don’t use the element you will save 100% of your hot water power requirements.

4. By How Much Will Replacing A Conventional Geyser With A Solar Powered System Reduce Electricity Consumption?

The electrical geyser uses on average between 30 – 50% percent of your household’s monthly electricity bill. Replacing your conventional geyser with a solar powered system will reduce that percentage of your electricity consumption by up to 70%.

5. How Hot Can The Water Get?

The ideal temperature of your geyser or tank is between 55 and 60⁰C. Most solar systems heat the water to between 55 – 65⁰C, but some can heat much higher than that. You need to be aware of over-performing systems so that you are not scalded by the hot water. Unless otherwise required the water temperature at the point of use should be at, at least 38⁰C for domestic fixtures such as baths, basins and showers and at least 45⁰C (in order to melt fats) for sinks. The temperature is not meant to exceed 55⁰ C at any point of use.

6. What Happens In Winter Or On Rainy Days, When There Isn’T Enough Sunlight To Heat The Water?

Solar water tanks are better insulated than electrical geysers and can keep water hot for a longer period of time. This ensures that there is always a tank full of hot water (and a backup of hot water) in the early evenings/mornings – provided the tank size is correct. An electrical backup system is allowed on the program provided it has a timer switch that ensures it does not operate during Eskom’s peak demand periods. Customers need to ensure suppliers/installers appropriately insulate all the pipes exposed to the elements to prevent freezing and heat loss.

7. Do I Need To Install A New Geyser, Or Can Solar Panels Be Added To The Existing System?

Standard geysers are not designed to be utilized with solar collectors as they do not have sufficient inlets and their linings are often not designed to withstand the temperature experienced from solar energy. The supplier should evaluate the existing geyser and, based on your needs, the supplier can evaluate the possibilities of using the existing system.

8. What Are The Life-Cycle Expectation Of The System And The Total Energy Savings On It?

Each piece of equipment has a different savings profile which depends on various elements such as geographical area, water usage profile, number of users and the size of the system. However, on a 200 liter system, the SABS average is 5.67kWh per day at 16MJ input power. The expected life of the equipment can range from 5 to 15 years; most systems are guaranteed for 5 years.

9. How Much Can It Save In Your Typical Electricity Bill?

A geyser uses between 30 – 50% of the electricity used in a home. Typically taking overcast weather and usage patterns into account, 70% of this energy can be displaced by a solar system.
Given our current electricity shortage, how much can solar water heaters help reduce demand?
If 100,000 geysers were to be installed this would offset 300 MW worth of connected load. However if we take diversity and usage into account this equates to a 63 MW load that is actually removed during our peaks. Read more to see how much electricity you’ll be saving in one year by converting to solar.

10. How Much Can It Save In Your Typical Electricity Bill?

A geyser uses between 30 – 50% of the electricity used in a home. Typically taking overcast weather and usage patterns into account, 70% of this energy can be displaced by a solar system.

11. What Is The Typical Payback Period For A Solar Water Heater?

With the current rebates in place paybacks are typically between 5 years or less, depending on geographical area, water consumption patterns, number of people in the household, type of system chosen and energy cost. However, our finance service makes it easier and better for you.
